Some interesting behaviour with IQ180 when shifting. I suspect this is how things work, but would love to know if there is something I am missing here.
Shooting with IQ180/90HRSW with polarizer
Two frames, first 15mm left/ 0mm vertical, second 15mm left 30mm down
WB in back set to Daylight
Imported into C1, WB shows as 5000K, 0 tint on both frames
After LCC is applied, there is a significant shift in color in both frames.
Camera was in same position for both shots, only difference is the shift.
Exposure was the same for both frames as well.
I thought there was a shutter sync issue, but I have several scenes where the same behaviour can be seen.
I also tried white balancing the LCC before applying and it gets a little better, but still a large difference. In the second set below, I manually corrected as best as I could, but still not close enough.
1. Is there something I am missing at capture time? Can I do anything differently here. I guess the most obvious would be to shoot a grey card in each frame, that that gets hairy along with all the other things I need to do like shooting LCC, exposure bracketing etc.
2. How can I get this better in post-processing in C1? Is there an easy way to match these? I had assumed WB off the sensor was an absolute value, but it appears not to be. What is the easiest way to match WB across two frames?
Appreciate your thoughts.
LCC applied - NO other corrections - no changes except shift - same exposure
White balanced LCC applied - C1 manual matching of WB, exposure, same exposure at capture.
BTW, I now see a centerfolding issue in the first frame, but lets ignore that for now
